If inner receptacles are not leakproof, what is the proper course of action before shipping?

• A. Continue shipping with external protective measures.
• B. Replace with leakproof inner packaging and add secondary containment.
• C. Only label the package more prominently.
• D. Switch to a non-hazardous material.

Answer: (B)

When shipping liquids or other potentially leak‑producing contents, the inner receptacles must be leakproof to prevent any escape of contents during handling and transport. If they aren’t leakproof, the correct course is to replace them with leakproof inner packaging and add secondary containment. This combination creates a robust barrier: the leakproof inner packaging keeps the liquid from leaking out, and secondary containment (a leakproof outer package with absorbent material and proper closure) catches any leakage that might occur, protecting people, other packages, and the environment.

Rushing to ship with only external protective measures or simply labeling the package more prominently does not address the real risk of leakage. Switching to a non-hazardous material isn’t a valid option unless the material truly qualifies as non-hazardous. The leakproof inner packaging plus secondary containment approach aligns with safe-handling practices and packaging regulations, ensuring the shipment remains contained under transport conditions.
